Transparent Post-Its let you see what you’re editing

Genius….

DVICE:

“It’s not often you see an innovative twist on an already good idea,
but 3M’s done it with their transparent Post-It notes. Called Sheer
Colors, the see-through notes have a host of uses — from highlighting
borrowed books to marking up photographs without actually defacing
them. They also might be a decent choice to cover the eyeholes in your Iron Man mask.”
